" 8 Claims. (crass-+152) The device forming the subject. matter of this application is a hosenozzle. Theinvention aims toprovide a straightaway nozzle in which there will be no distortion of the flow, friction being 5' out down accordingly. Another object of the invention is to provide novel means whereby a disk through whichthe liquid flows may be renewed at willr A further object of the invention is to provide novel means for securing a strongclamp- 10 ing. actionqon. the disk, leakage being prevented but the: constructionbeing such :that, in the event of abnormal pressure, relative longitudinal movement may .tagkez.-place between the outlet member and the'casing: of the nozzle,ther-eby 1'5 relieving abnormalpressure. .A further object of the inventionisto supply a deviceof the class described which will be .substantially self-cleaning. Another object .of. the invention is to supply a nozzle in which high working pressures 20 are possible without leakage or undue wear. The

invention aims, further,.to improve and to enhance the utility of devices ofath'at type to which it appertains- 1. With the above. and other objects' in-view, 25 which will appear as the description proceeds,

the invention resides ,inthe combination and arrangement ofparts and in. the:- details of' construction hereinafter described and claimed, it being understood that changes inthe precise eni- 30 bodiment. of the invention herein disclosed, may be made within the scope of what-is claimed, without departing from the spiritof the invention.

Referring to Figs. 1 to 6, there is shown a twopartcasing, which, in Fig. 1, is denoted generally by the numeral l. The casing l comprises a-butt 2. At one end, the butt 2 has an internally threaded portion 3 enabling the device to be connected to a hose (not shown). Adjacent to the threaded portion 3, the butt 2 has an internal recess 4, receiving a compressible washer 5. The butt 2 has a reduced neck 6 forming a transverse, external, circumferential shoulder 10 I. The end wall 8 of the neckfi of the butt 2 may be referred to as an internal transverse partition in the casing I, and is formed integrally with the neck. The end wall or partition 8 carries a central pointed spreader stud 9, projecting toward the inlet end of the butt 2, as shown in Fig. 1.: Ports 10 are formed in the partition 8 of the butt 2. Theseports ID, in Fig. 6, are shown as disposed on opposite sides of the stud or spreader 9. But two of the ports ID are delineatedgbut it will be understood that there may be as many or as few of said ports as may be desired.

The casing l comprises a tubular body ll. At its out'er'end, the tubular body II has an inwardly-projecting circular flange l2. The-flange I2 is supplied with a parti-circumferential, external rib l4 (Figs. 1 and 3), the ends of the rib constituting stops I5; The inner end of the tubular body His disposed about the neck 6 of thej butt 2, as shown-in Fig. 1, and is connected thereto by a securing device [6, such as a screw. outlet member H is provided, and is a composite structure. The outlet member I! comprises a tube l8 journaledin the flange l2 of the body II of the casing. Thetube 18 carries a stud or screw l9 (Fig. 3), the stud constituting a stop; adapted to engage the shoulders l5, the intere'ngageable parts l5. and I9 coacting to limit the rotation of the tube [8 ma way which will 40 be evident from Fig.3. H

The tube l8 has an enlarged foot 20, received rotatabl y within thebody l I of the casing I The foot 20 forms an external circumferential shoulder 2| onthe tube I81 The foot '26 has; an integral end wall 22," whichmayybe denominated an internal partition in the outlet member 41. The partition 22"-is provided with ports 23. The ports 23 are adapted to register with the ports II] in the partition '8 of the butt 20f the casing I. '50

A renewable disk 24 fits within the tube I8 between thepartitipn 8 ojfthe butt 2 and the partition 22 of the tube t8.- The disk 24 has openings, in which are fixed tubular-rnetal connections 25, received detachably in the ports 23 of the partiprevent wear, as the water or other the tube tion 22 of the tube I8. Thus, the disk 24 is connected to the partition 22 for rotation when the tube I8 is rotated. The disk 24 maybe made of fibre or similar material, which is subject to wear. The tubular connections or thimbles 25, however, liquid passes through them. j It is not necessary that the tubular connections 25 be employed. In Fig. 7, parts hereinbefore describedhave been designated by numerals previously used, with the suffix a. In this form of the invention, the disk 24a may be made of metal or the like, and under such circumstances, the disk carries dowel pins 26, engaged in open ings 2'! formed in the end wall 22a, of the tubular member I8a.

Reverting to Fig. 1, a ball bearing 28 is'disposed about the tube I8, within thebody II... .The ball bearing 28 abuts against the flange I2 on -the body II. A compression spring 29 surrounds a portion of thetube I8 and is disposed within the;tubular body I I of the casing I. One end of the compression spring 29 abuts against the ball bearing 28, and the opposite end of the compression spring abutsagainst the shoulder 2| on the foot 20 of the tube I8. A divider 30 is disposed within I8, and is secured thereto. The divider 30 is in the form of a plate, shown as extending from the outer end of the tube I 8 to a point close- 1y adjacent to the partition 22 of the tube. The divider 38, however, may be spaced from the partition 22 of the tube I8 to any desired extent.

A spout 3| is provided, and has an enlarged portion 32, engaged with threads 33 on the tube I8. A washer 34 is compacted against the end of the tube I8 by the spout 3 I. A channel ring 35 is engaged with the threads 33 of the tube I8 and serves as a lock nut which prevents the spout 3| from threading off the tube I8. The channel ring 35 carries a grip ring 36, which may be made of rubber or other suitable material, the ring 36 constituting means whereby an operator may rotate the tube I8. Y

In practical operation, the tube I8 is rotated by means of the ring 38, and the renewable disk 24 is rotated also, owing to the presence of the tubular connections 25, until the said connections register with the ports ID in the end wall 8 of the butt 2. Then water or other liquid can flow through the nozzle. The liquid is directed toward the ports ID by the stud 9. Having passed through the ports I8 and the tubular connections 25, the liquid flows through the tube I8, on each 'sideof the divider 38, the divider 38serving to prevent a whirling motion, as the liquid leaves by way of the spout 3I. When the tubular connections 25 are aligned with the ports ID, the stop I 9 on the tube I8 is in engagement with one of the shoulders I of the body I I, and when the tubular connections 25 are not in registration with the ports I 0, the stop I9 is in engagement with the other of the shoulders I5, all of whiohwill be understood readily when Fig. 3 of the drawings is noted. V V

The function of the spring 29 is to bind the renewable disk 24 tightly between the partition 8 of the butt 2 and the partition 22 of the tube I8. The spring 29, however, has another function, in that, when the ports I8 are closed, if there is an abnormal pressure behind the partition 22 of the tube I8, the tube can move forwardly a little, thereby spacing the parts 24 and I8, pressure thereby being relieved. The ball bearing 28 fa-' cilitates the rotation of the tube I8 with respect to the casing I. I I

In Fig. 8, parts hereinbefore described have been designated by numerals already used, with the sufi'ix b.

The body IIb and the butt 2b of the casing Ib are formed in one piece. The channel ring 35b is formed integrally with the tube I8b.

The partition 22b of the tube I8b carries a guide neck 31 in which reciprocates a post 38, threaded at its inner end into the central portion of the partition 81), the end of the post constituting the point of thestud or spreader 8b. An abutment nut 39 is threaded on one end of the post 38. A compression spring 48 surrounds a portion of the post 38. One end of the compression spring 40 abuts against the guide neck 31, and the opposite end of the spring abuts against the nut 39 on the post 38.

. The operation of the device shown in Figs. 8 and 9 does not differ in many respects from the operation of the device shown in Fig. l. The spring 40 can yield, like the spring29, .and for the same purpose, and constitutes means for holding the ported parts 22b and 8b in binding relation to the disk 24b, the spring 40 being internal with respect to the tubular member I8b, instead of external thereto, as shown in connection with the spring 29 and the member I8 of Fig. 1.
